911 recording released Wednesday reflects frantic moments after Houston found

"I need paramedics," said the hotel security officer who found Houston in the bathtub

A woman in Houston's room was "pretty much out of it," the guard tells the dispatcher

Beverly Hills police agree with coroner's report that Houston's death was accidental drowning

The police investigation of Whitney Houston's death is "officially closed" with the conclusion that her death was an accidental drowning, the Beverly Hills Police Department said Wednesday.

With the case closed, police released the recording of the 911 emergency call in which a hotel security officer said the woman who called for help from Houston's room was "irate and pretty much out of it."

Investigators "found no evidence of foul play," a police statement said. "Based on the findings of our investigation and our review of the coroner's report, we have determined that this is not a criminal matter."

The Los Angeles County coroner released its autopsy report a week ago saying Houston's February 11 death was an accidental drowning with the "effects of atherosclerotic heart disease and cocaine use" as contributing factors.

The Beverly Hilton security officer did not identify Houston in the 911 call.

"I need paramedics, apparently I've got a 46-year-old female, found in the bathroom," he told the 911 operator. "That's all I've got right now, but they're requesting paramedics." (Houston actually was 48).

The autopsy report said her assistant found Houston face down in a tub of "extremely hot water" about 12 inches deep.

"I'm not sure if she fell, or if she was in the bathroom with the water," the hotel security officer is heard saying in the 911 call.

And you don't know if she's conscious or breathing at all?" the dispatcher asked.

"Apparently she wasn't breathing," the hotel employee said.

When the dispatcher asked if she had started breathing, the security officer said "I don't know. The person that called me was irate and pretty much out of it."

"Can you get me into the room so I can try to give CPR instructions?" the 911 operator asked.

"No, because she kept hanging up on us," the hotel security officer said.

Houston was last seen alive by her personal assistant in her Beverly Hilton hotel room about 3 p.m. that Saturday, the autopsy report said. The assistant left to run errands after telling Houston to take a bath in preparation for a pre-Grammy Awards party at the hotel that night, it said.

When the assistant returned to the locked room at 3:35 p.m., she found Houston "lying face down in the bathtub filled with water, unresponsive."

"The assistant called for her bodyguard, and together they pulled the decedent out of the bathtub," the report said.

When paramedics arrived about 10 minutes later, they moved Houston to the living room floor. It was at 3:55 p.m., 20 minutes after she was found by the assistant, when paramedics concluded she was dead, the report said.

The coroner's report stopped short of detailing what happened to Houston, but HLN's Dr. Drew Pinsky, an addiction medicine specialist, examined the autopsy report for CNN and suggested that she might have suffered a seizure brought on by the use of cocaine, possibly combined with a withdrawal from alcohol and a prescription sedative.

An empty bottle of the anti-anxiety drug Xanax was found in her room, but the level of the sedative found in her blood was low, he said. Empty beer bottles were also found, but alcohol was not detected in her body, he said.

"To me, a sudden drop-off in the Xanax level, a drop-off in your alcohol consumption, add cocaine, that's a recipe for a seizure," Pinsky said. "Somebody who's now upside down in a bathtub could easily seize and drown."

However, Henry Spiller, a toxicologist and director of the Kentucky Regional Poison Control Center, said the level of Xanax found in Houston's blood was not low enough to trigger a seizure. Those who abuse Xanax can take up to 20 pills a day, he said, and the level found in Houston's body would indicate she took four to six pills several hours before she died.

Since the drug was found in her blood, a seizure brought on by withdrawal is unlikely, he said.

The coroner's report notes that Houston suffered several small scald burns on her face at the time of her death.

A 60% narrowing of her arteries found in the autopsy is "very mild heart disease," Pinsky said, which should not have caused a problem.

Spiller said that based on his experience with cocaine abusers, two things may have happened: Either Houston had a seizure and fell into the tub, or she had a cardiac arrhythmia. An arrhythmia occurs when the heart stops beating properly and fails to pump, depriving the brain of oxygen and causing a loss of consciousness. It can be fatal.

"If you look at cocaine deaths, more deaths are from arrhythmias than seizures," Spiller said. "Based on what is in the report, it seems more likely that she had a vasospasm (which shuts off blood flow to the heart) or a fatal arrhythmia."

Toxicology testing measured 0.58 micrograms of cocaine per milliliter of blood drawn from a vein in her leg during the autopsy, which Pinsky called a moderate level.

Spiller said for that level of cocaine to be in Houston's body, "we're talking about approximately half a gram of cocaine having been possibly ingested within 30 minutes to 90 minutes before her death. For someone who has been abusing cocaine, this may be their routine amount, but (for) someone who doesn't regularly use cocaine and therefore doesn't have a tolerance for the drug, this would be a high level."

Houston's cocaine use appeared to have occurred "in the time period just immediately prior to her collapse in the bathtub at the hotel," Chief Coroner Craig Harvey told reporters when he released the preliminary report last month.

Investigators found "a small spoon with a white crystal like substance in it and a rolled up piece of white paper" in the bathroom where Houston drowned, coroner's investigator Kristy McCracken wrote.

"Remnants of a white powdery substance" were found on a bathroom counter, McCracken wrote.

"I also collected remnants of a white powdery substance from out of a drawer and from the bottom of a mirror in the same drawer in the bathroom counter," she wrote.

Detectives found a "plethora of medications bottles" in the hotel room, although the coroner concluded the prescription drugs "did not contribute to the death."

Along with cocaine and Xanax, the toxicology tests found other drugs in her body, including marijuana, the muscle relaxant Flexeril and the allergy medicine Benadryl, the report said.

Houston won six Grammys and sold 170 million albums, singles and videos over her career.

In recent years, the singer's accomplishments were overtaken by her struggles with drug addiction.
